If you move your business to Hawaii — or sell into the state from the mainland — and treat its tax like an ordinary sales tax, you will underpay it, misreport it, and possibly overcharge your customers while doing so. Hawaii has no sales tax at all. What it has instead is the General Excise Tax (GET): a tax on you, the business, measured on nearly every dollar of gross income you earn, whether you sell products, perform services, collect rent, or earn a commission. It applies even when you lose money, because there are no deductions for expenses.
Here is how the GET actually works, what rate you really owe, why your receipt shows 4.712% when the law says 4.5%, and how to stay compliant.
How the GET Differs From a Sales Tax
The GET is authorized under Hawaii Revised Statutes Chapter 237 and is classified as a privilege tax on the act of doing business in the state — not a tax on any individual purchase. In a conventional sales-tax state, the buyer owes the tax and the seller merely collects it on the government's behalf. Hawaii flips that relationship: the business itself owes the tax, calculated on its gross income from all commercial activity.
Three consequences follow from that design, and each one surprises newcomers:
It covers almost everything. Because the tax falls on the privilege of doing business rather than on retail transactions, it reaches services, rentals, commissions, contracting, and interest income that a mainland sales tax would skip. A freelance designer, a landlord, and a real estate agent all owe GET on their receipts. Activities escape the tax only when the law explicitly exempts them — the default is taxable.
It taxes gross receipts, not profit. Payroll, rent, materials, subcontractors — none of it is deductible. If your costs exceed your revenue in a bad year, you still owe GET on every dollar that came in. This is the single most important planning point for low-margin businesses: a 4.5% levy on gross receipts can exceed your entire net margin.
You may pass it on, but you don't have to. Whether you add the tax to customer invoices is a matter of private agreement between you and your customer. Many businesses do, but if you absorb it, you still owe it — and you may not advertise that you charge "no tax," because the tax exists regardless of who visibly pays it.
The Rates That Actually Apply
The statewide base rate is 4% on retail sales, services, rentals, commissions, and most other business income. But almost nobody pays exactly 4%, for two reasons: a lower wholesale tier and county surcharges.
The 0.5% wholesale tier
Wholesaling, manufacturing, and producing are taxed at just 0.5%. If you buy goods for resale from a licensed supplier, that wholesale transaction is taxed at the half-percent rate while your retail sale to the end customer is taxed at the full rate. To buy at the wholesale rate you generally need a GET license and must provide a resale certificate — without one, your supplier must treat the sale as retail.
County surcharges bring everyone to 4.5%
Each county may impose a surcharge of up to 0.5% on top of the state tax, and as of 2026 all four counties sit at the full 0.5%: Honolulu (Oahu) since 2007, Kauai since 2019, Hawaii County (the Big Island) since 2020, and Maui since 2024. That makes the combined rate effectively 4.5% statewide. The Honolulu, Maui, and Big Island surcharges are currently authorized through December 31, 2030.
Which county's rate applies depends on where the business activity occurs — not where your office is. A real estate agent based on Maui who earns a commission selling a condo on Oahu owes the Oahu rate on that commission, because the property (and the taxable activity) is there. If you do business in more than one county, you allocate the tax across districts when you file.
Yes, groceries are taxed at the full rate
Unlike the majority of states, Hawaii taxes food at the full GET rate with no grocery exemption. Lawmakers introduce bills to exempt or phase down the tax on groceries nearly every session — a 2026 proposal would step the rate down starting in 2027 toward a full exemption in 2034 — but as of now none has become law. If you sell food at retail, budget for the full rate.
The 4.166% and 4.712% Mystery, Explained
Every visitor to Hawaii eventually stares at a receipt and asks: if the rate is 4% (or 4.5% on Oahu), why does the receipt say 4.166% (or 4.712%)? The answer is the pyramiding effect, and understanding it matters because it caps what you may legally show your customers.
Because the GET is imposed on your gross income — which includes whatever amount you passed on to the customer — charging a flat 4% leaves you short. Sell something for $100, add $4.00 labeled as tax, and you now owe 4% on $104.00, or $4.16. You collected $4.00 but owe $4.16. To recover the full liability through the pass-on, the math works out to 4.166% at the 4% rate and 4.712% at the 4.5% rate.
Hawaii publishes these as maximum visibly-passed-on rates, and that word "maximum" has teeth:
- Passing the tax on is optional, but the cap is not. If you separately state the tax on an invoice or receipt, the amount shown cannot exceed what the rate allows. Stating more than the lawful pass-on rate can be treated as an unfair or deceptive practice.
- Absorbing the tax doesn't erase it. A business that folds the GET into its prices still owes the full amount and may not claim it charges no tax.
- Some businesses can't pass it on at all. Insurers, for example, are barred by statute from tacking GET onto premiums, and prices fixed by law leave no room for a pass-on line.
The practical takeaway: if your point-of-sale system or invoicing template lets you type any "tax rate," make sure it uses 4.166% or 4.712% as appropriate — not 4% or 4.5%. The former under-recovers your liability; anything above the cap overcharges the customer.
Getting Licensed and Filing
Before you do any business in Hawaii, you must obtain a GET license by filing Form BB-1 with the Department of Taxation and paying a $20 one-time license fee. The license must be displayed at your place of business. Operating without one can cost you the exemptions, deductions, and lower rates you would otherwise qualify for — the department can simply deny them.
Filing frequency and forms
You file periodic returns on Form G-45 and an annual reconciliation on Form G-49. The department assigns your filing frequency based on your expected annual liability:
- Monthly, if you expect to owe more than $4,000 per year
- Quarterly, for mid-range liabilities
- Semi-annual, if your annual GET will be $2,000 or less
Periodic G-45 returns are due on the 20th day of the month following the close of each filing period. The annual G-49 reconciles the whole year and is due April 20 for calendar-year taxpayers. Two rules catch newcomers: you must file a return for every period even with zero taxable sales, and if you operate in multiple counties you must allocate the tax by district (the G-75 schedule) so each county's surcharge lands correctly.
Most filers submit electronically through Hawaii Tax Online, which handles registration, G-45 and G-49 filing, and payment in one place.
Remote sellers: economic nexus applies
Since Act 41 of 2018, you don't need a physical presence in Hawaii to owe the GET. An out-of-state seller is considered to be doing business in Hawaii — and must get a license, file returns, and remit the tax — if it has $100,000 or more in gross income from Hawaii sources or 200 or more Hawaii transactions in the current or preceding calendar year. Marketplace facilitators face the same thresholds. If you sell online into Hawaii at any real volume, check your Hawaii-sourced sales against those two numbers.
Don't forget the use tax
The use tax is the GET's backstop: it applies at matching rates (4% for goods imported for personal use or consumption, 0.5% for goods imported for resale) when you buy from an unlicensed out-of-state seller that didn't charge Hawaii tax. It is due by the 20th of the month after the goods enter Hawaii, and you can credit sales or use tax you already paid to another state on the same purchase.
Mistakes That Cost Hawaii Businesses Money
Treating the GET like a sales tax in your books. The most expensive error is recording only the tax you "collected" as your liability. Your liability is computed on gross receipts including any passed-on amounts. If your bookkeeping treats the pass-on line as a trust-fund collection (like mainland sales tax) rather than part of taxable gross income, your returns will understate what you owe.
Skipping the annual G-49. Businesses that faithfully file every G-45 sometimes treat the year as done — then miss the April 20 reconciliation. The G-49 is where underpayments surface, and filing it late draws penalties on top of the balance due.
Filing zero-sales periods late — or not at all. A quiet month still requires a return. Seasonal businesses (tourism-adjacent shops, wedding vendors, winter-only services) rack up failure-to-file penalties during the off-season by assuming "no sales, no return."
Applying the wrong county rate. Businesses with customers across islands sometimes report everything at their home-county rate. With every county currently at the same 0.5% surcharge the dollars net out today, but the allocation still matters for the record — and rates can diverge when authorizations expire.
Operating on someone else's license. Contractors and market vendors occasionally operate under a general contractor's or event organizer's license. Hawaii requires each person doing business to hold their own license, and working without one forfeits your exemptions and wholesale-rate eligibility.
Tracking GET Cleanly in Your Books
Because the GET is a tax on your gross income rather than a pass-through collection, your chart of accounts should reflect that reality. Record the full amount the customer pays — including any separately stated pass-on — as gross revenue, and book the GET you remit as a tax expense. Blending the pass-on into a generic "sales tax payable" account, mainland-style, misstates both revenue and expense.
Businesses operating on multiple islands should tag income by county or district at the transaction level, so the multi-county allocation practically writes itself at filing time. And if you pass the tax on, reconcile the pass-on collected against the GET actually paid each period — the pyramiding math means the two should match only when your stated rate is exactly right. A persistent shortfall means your invoiced rate is too low; a persistent overage means you may be overcharging customers. Either way, the dashboard views in Fava make it easy to spot the drift before it compounds across quarters.
Simplify Your Financial Management
Doing business in Hawaii means living with a tax that touches nearly every dollar you earn, follows you across county lines, and punishes mainland assumptions. Keeping clean, county-tagged records of gross receipts and GET paid turns the G-45 from a monthly scramble into a routine export.
